In addition, Calomera sturmi (Ménétriés, 1832), Bembidion (Nepha) menetriesii (Kolenati, 1845), Bembidion (Peryphus) obscurellum turanicum (Csiki, 1928), and Lionychus (Lionychus) orientalis (K.Daniel, 1901) are reported from the Alburz Province for the first time. Microlestes plagiatus (Duftschmid, 1812) is reported from the Mazandarn Province for the first time and Myriochila (Myriochila) semicircumcincta (Mandl, 1959) is reported from Hormozgan Province for the first time.
